Partimage is not currently under active development, so don't expect new features to be implemented. Hopefully someone will get the project going again or a similar app.

The surest way to do what you want is to purchase one of the windows-centric cloning solutions. If you or the community center doesn't have the budget for that, perhaps there is a more technical person there who can do it with free software like partimage, clonezilla, systemrescueCD or simply dd. If you have a variety of different machines, it will be very difficult to automate the process. Good luck.
